Key takeaways
Your bank balance does not tell the full story
A savings account can show more euros each year thanks to interest, while those euros buy less if prices rise faster.
The key is comparing the net rate with inflation
A savings product truly protects purchasing power only if its net rate is higher than inflation. A positive rate is not enough.
In 2026, figures can change quickly
As of June 2, 2026, the Livret A rate is 1.5%, the LEP rate is 2.5%, and French inflation for May 2026 is estimated at 2.8% year-on-year. These figures should be reviewed regularly.
